World Series

The World Series was a baseball championship series on Earth during the 20th and 21st century. A best-of-seven playoff, the Series was contested between the winners of the two established leagues. The Series took place on a yearly basis (excepting 1904 and 1994) from 1903 to 2042.

Suggested by the addition of the London Kings, international teams were included in the World Series beginning some time in the 21st century. It is unknown whether they were the result of the expansion of North America's Major League Baseball enterprise, or an expansion of the World Series itself to involve one or more future international baseball leagues.

The event had a much brighter future in the novel Spock's World, where Sarek had attended a World Series game in 2180.
